It actually looks like it's simpler than what I did for
libubootenv_%.bbappend in last email ... since I'm using poky distro and it
looks like u-boot-imx.bb is including that
(recipies-bsp/u-boot/u-boot.inc), simply adding " SRC_URI += "
file://fw_env.config" " is all that's needed (with a fw_env.config file in
files dir of course) in u-boot-imx_2020.04.bb ... but again, I do a bitbake
core-image-minimal and go look at tmp/deploy/images/imx8mmevk and the time
date stamp on my core-image-minimal-imx8mmevk-squashfs has not changed but
it has on a fw_env.config file sitting right in the directory ... which is
not where I want it!  It should be in the squashfs.
